ABSTRACT:
The curtain consists of a single, translucent, yet untransparent fabric sheet, hung to sliders carried by a track, the latter track anchored in horizontal position against a vertical wall above a window frame. A cord at the end of the track operates the sliders to both slide the curtain sheet lengthwisely of the track, to fold/unfold in accordeon like the curtain sheet for extending/retracting same, as well as tilt the sliders about their vertical axes, as with a vertical blind actuating mechanism. The drape has a wavy configuration, whereby as the sliders are pivoted by the control cord, the amount of light traversing the drapes will adjustably vary in a progressive fashion. Each slider includes a cardboard plate, lodged into a pocket made at the top edge portion of the drapes, and releasably engaged by a slider hook.
